Why the Introduction Sets the Tone for Your Whole IA
The introduction is your IA’s first impression.
It’s where examiners decide whether your exploration feels authentic, mathematical, and focused.
A great introduction doesn’t just explain what you’ll do — it shows why it matters and how you’ll use mathematics to explore it.
In short, it blends curiosity, structure, and purpose.
Using RevisionDojo’s IA/EE Guide, Exemplars, and Topic Planner, you can write an introduction that stands out while aligning perfectly with the IB rubric.
Quick-Start Checklist
Before writing your IA introduction:
- Choose a topic you’re genuinely interested in.
- Review RevisionDojo Exemplars for tone and structure.
- Write a clear rationale for your investigation.
- Identify which mathematical areas your topic involves.
- Draft a concise research question or aim statement.
Step 1: Start With Curiosity
Begin with a short, personal motivation — something that shows why the topic grabbed your attention.
Example:
“As a tennis player, I’ve always been fascinated by how spin affects ball trajectory. This exploration uses parametric equations to model the path of a topspin serve.”
RevisionDojo’s IA/EE Guide includes phrasing templates to help you express genuine interest without sounding forced.
Step 2: Define the Context Clearly
After the hook, ground your reader in context.
Explain the situation you’re exploring in simple, clear terms.
Example:
“The trajectory of a spinning tennis ball depends on initial velocity, launch angle, and air resistance. This investigation explores these factors through mathematical modeling.”
